This pointer was always null since the changes of 4519d8e08a (Remove
wxUSE_UNICODE checks as they're always true now, 2022-10-27), so remove
it completely.
Override required functions in wxHeaderCtrlSimple to avoid asserts if
its columns are reordered.
Also bring the code behaviour in agreement with the documentation by
calling UpdateColumn() after calling UpdateColumnVisibility().
Finally, only call UpdateColumnsOrder() if the corresponding event was
not processed as the application should use one xor the other mechanism
for reacting to columns reordering, but not both.
Closes#24108.
Closes#24172.
All currently supported versions of MSVS support POSIX "%g", "%G", "%V"
and "%z" format specifiers, so do call strftime() even if they are used
in the format string.
However don't do this when using MinGW, as its CRT still doesn't support
them.
Although building CEF itself requires C++17, C++14 is sufficient for
building libcef_dll_wrapper, so allow using it.
Also move the error message a bit more informative.
If it is enabled (e.g. globally because the application using wxWidgets
as a submodule enables it), it would result in a harmless warning about
not calling the base class ctor in base/cef_callback_internal.cpp.
We don't have DISABLED_UTILS or DISABLED_DEMOS variables, so it's
useless to exclude them from the makefiles list -- just stop doing it.
This fixes a problem with using EGREP without preceding AC_PROG_EGREP
with autoconf 2.72, as EGREP is not defined any longer with this
version.
See #24168.
Non-integral coordinates and overlay scrollbars can cause the event to be
generated with coordinates that are still inside the window. Avoid this by
ensuring that integral coordinates are outside the window, and ignoring overlay
scrollbars. Also remove gdk_display_flush(), contrary to the very old comment
it does not seem to be necessary. Fixes wxScrolledWindow auto-scrolling.
Remove installed event handlers before trying to hide the popup,
as this could result in Destroy() being called twice under wxQt.
This happens to wxRichToolTip for example. i.e. Destroy() is called
once from wxPopupFocusHandler::OnKillFocus() after the call to Hide()
then, from wxRichToolTipPopup::OnTimer().
The fact that we cannot create a wxPopupWindow with a parent
is no longer valid after the recent changes to the wxQt port.
The wxRichToolTip (an instance of wxPopupWindow) will crash if
created without a parent under this port.
Try making this test more robust as well as it also sporadically fails
on AppVeyor.
Also simplify it a bit, checking for each of the expected events in turn
instead of checking for their total number at the end.
If possible, all windows should call wxWindow::Create() on creation now,
because among other things:
- It manages generic and non-generic windows uniformly and transparently
- It ensures an appropriate initial size for the window
- AddChild() and PostCreation() are automatically called
- Scrollbar policies are set in one place.
This didn't work under wxOSX or wxGTK/Wayland as it used wxClientDC
which doesn't work in these ports.
Fix this in the usual way, i.e. by just redrawing everything in them.
In this case we can still use wxClientDC, so let people do it if they
really want to for consistency with wxSplitterWindow and because it
doesn't really cost us anything.
Use wxClientDC instead of wxScreenDC, which only works in wxMSW, and use
wxINVERT instead of wxXOR, to make DrawResizeHint() actually draw
something in wxGTK3 too.
And not using wxScreenDC might even help with some problems under MSW
too, see #23982.
Note that "rectangle hint" code still uses wxScreenDC, but this hint
kind should probably be just removed as it doesn't seem useful for
anything.
This is similar to wxAuiManager::AlwaysUsesLiveResize() and does the
same thing, i.e. returns true if live update is always used, whether
wxSP_LIVE_UPDATE is enabled or not.
Use the new function in the sample to disable the menu item in the
environments where it doesn't do anything, as it was confusing to have
it under e.g. Wayland.
This function can be used to check if drawing on wxClientDC actually
works. This has to be a run-time, rather than compile-time, check
because in wxGTK3 this depends on the backend being used: wxClientDC
only doesn't work with Wayland, but does work with X11 (and, less
importantly, Win32) backend(s).
Currently the wxWindow parameter of this function is not used but it
could be useful in the future and it will be simpler to allow not
specifying it (by defaulting it to nullptr) than to add it later, so it
seems better to have it.
No real changes, just write a single check for "dc == nullptr" instead
of doing it twice in combination with preprocessor checks.
This commit is best viewed with Git --color-moved option.
There is no longer a QtGetContainer() function name. wxQtEventForwarder was renamed
to wxQtEventSignalHandler. And QtGetScrollBarContainer() was just removed in previous
commits.
Because It is simpler to initialize (the inherited) m_qtContainer member
directly in derived classes during construction process, and make the API
a little bit cleaner.
Neither QListWidget nor QTextEdit derive from QScrollArea and the cast to it is
just UB. Instead, using the common base class QAbstractScrollArea is safer and
eliminates the need to these dangerous and insidious crosscast'ings.
